GSL Twin System
Our twin 4" stainless exhaust system's are our most popular exhaust by far for the 79 series Land Cruiser crowd.
It is what we like to call the full GSL treatment because it produces the sound we’ve worked so hard to achieve. Plus, it’s the sexiest system we offer by far; twin, brushed stainless steel and 4 inch pipe? Yes please!
If you plan on getting a cruiser, chances are you plan on giving it a bit of a hammering, whether it be off-roading, camping, beach driving, Hill climbing or something of the likes. We’re exactly the same, and because of this, we strive to make sure our exhausts are built to withstand the toughest adventures. High quality 304 grade 4’’ stainless steel, sturdy custom folded bracketry, and top quality welding work.
Hand made by true 4x4 lovers
At GSL, all of our piped systems (exhausts, engine upgrades etc.) are made compeltely by hand. With 7 years of perfecting and adjusting these system one bend at a time, our reputation for outstanding quality products will speak for itself. Not to mention, it looks fantastic! All of our products are Australian made and sourced, so you’ll be supporting local aussie suppliers.
The ‘Turbo back’systems are great for pre DPF models (pre-2017).
They give the nicest note, and best performance gain of all exhaust types, however more recent models are legally required to have a DPF in place. This variant removes the DPF entirely and in most areas, is an illegal modification - thereby voiding any warranty’s on the vehicle. This is an option for offroad and track use only.
The system starts with a 5 inch dump, moving into a 4 inch CAT, a 4 inch muffler section, and splits off into two 4 inch tails.

ELITE DPF SYSTEM (REQUIRES A REMAP)
Australian made upgraded DPF (Diesel Particulate Filter). The main reason for this mod is to give you the V8 note that standard DPF models are lacking. Being a high flow, this eliminates the bottlenecking issue with the standard DPF’s, and assures consistent power with no drawbacks.
This option is great for everyday use, keeping your vehicle compliant with vehicle emission standard.
The system starts with a 5 inch dump, moving into a 4 inch Elite DPF Section a 4 inch muffler section, and splits off into two 4 tails.
The Elite DPF system is an in house only, we cannot post this exhaust system as it does require remapping by GSL.
This system utilises the standard DPF, while still delivering the great note of our exhausts. If you’re chasing sound over performance, then this is the perfect exhaust. From the back it’ll look just as good, so you don’t miss out on aesthetics either!
This option is great for everyday use, as it’s a little quieter and keeps your vehicle complient with vehicle emission standards.
The system starts with a DPF to 4 inch adapter section, moving into a 4 inch CAT, a 4 inch muffler section, and splits off into two 4 inch tails.1 / 4 4 / 4

Absolutely love it, the boys work at gsl are the best of the best when it comes to things like this and I can’t recommend them enough, keen to travel around Ausralia with everyone hearing me coming into camp with a nice cruiser note! Let the good times roll 🤙🏻
Lads done a good job as always 👌
The guys at GSL seriously know what they're doing. I got the Turbo Back System along with some other upgrades, and my cruiser sounds EVIL after this. Can highly recommend this to anyone looking for an exhaust upgrade.
